For those who may be averse to cloud-based password vaults, here is a cake-and-eat-it-too solution.

The other great idea I read a long time ago came from Rachel Tobac: salt your passwords with a short bit you have committed to memory. This means the passwords stored in the vault are incomplete; you manually enter your 'salt' at the beginning or end of the stored password when logging in. If your vault is ever compromised, the passwords are useless.
@voltronic - the first is useless (csv handles this) the second is annoying, but will work until a site is breached.
After that, you're relying on the obscurity of being 1 in a million that somebody wouldn't try more than once. If you're a high value target to somebody... That obscurity goes out the window faster than somebody who kicked Putin's dog.
